JAMES F. MARSHALL, or WHITINSVILLE, messaonusn'rrs; ASSIGNQRI To. WBLIT IN MACHINE WORKS, or WHITINSVILLE, MfisseeH-nsn'ms; A, coRr0RArIonoF MAS- EACHUSETTS Application filed October 7, 1930. sem no. 487Q0 5i This invention relates to spinning and twisting framesof the ring type and relates more particularly to the rings and ring holders used on such frames.

These rings are of two general types, those having horizontally disposed traveler flanges and those having vertically disposed'flanges. These spinning and twisting rings are made of very hard and finely polished steel'an'd are commonly mounted in sheet metal holders which in turn are secured to the ring rails extending along the sides of the frame. Holes are bored in these ring rails so that the spindles and bobbins may be moved relatively upward and downward through the rings to eflect the winding of the yarn or thread thereon. I I

With the horizontal flange rings, the travelers do no extend down as far as the ring rail and the holes in the rail need be only large enough to allow'free passage of the bobbin and the thread thereon. With vertical flange rings, however, the lower flange commonly extends downward to or below the top of the ring rail and the hole in the rail must be large enough to afford clearance for the lower portion of the flange and for the lower end of the traveler.

When vertical flange rings are substituted for horizontal flange rings, it has been heretofore necessary to rebore the ring rails, which was an expensive operation and not always feasible, or to provide new rails at an 6VIl larger GXPQIISG.

It is the general object of my invention to provide means for securing a vertical flange ring in operative position on a ring rail without necessitating the enlargement of the holes therein previously provided' for horizontal flange rings. To the accomplishment of this result, I provide ring holders so designed that the lower flange of the ring is supported well above the ring rail, with the result that no part of the ring or traveler can engage :the ring rail.

My invention further relates to arrangements and combinations of parts which will be hereinafter described, and more particularly pointed out inthe appended claims.

The ring 12 is'suppor-ted by inserting the ring into an opening in a ringholder 2011mtil a flange 21 ontlie ring engages thetop surface of the holder. I l

Ears 22 (Fig. preferably struck up from the top portion .of'the holder and firim ly engage the upper edge of the flange 21'' on" the ring, I preventiiig displacement thereof. 3 I I i Toavoid the" necessity of enlarging the holes 1 1 toprovide clearance when changing fi:o1i1' liorizontal to vertical type rings onrthe same frame; provide my improved ring holder;- with downwardly oiiset' supporting portions 23 having base portions 24' adapted to'jbe secured to tlie r ail l Q by the usual clamping's'crews'25L Y I v I I "With this construction,' all ,o tith'e' ring 12 and traveler T aresup'ported r/e11 above the upper'surface' in the-rail IQ and there is ample clearance for the traveler TL I Ininthus able to change over a spinningor twisting frame-from horizontal to vertical flange rings, simply by loosening the screws 25, removmg'the flat ring holders with the II horizontal flange rings and applying my improved ring holders with the vertical flange rings in raised position. a

It is thus possible to change a frame from horizontal to vertical type rings at a slight expenditure of time and labor and without moving the ring rails from the frame or performing any mechanical operations thereon. The changing of frames from onetype of rings to the other is thus greatly simplified and may be readily accomplished at any time and as often as desired.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is 1. In a ring spinning frame having a ring rail, a vertical flange ring having a supporting portion and having a traveler flange extending substantially above and below said supporting portion, a traveler for said ring having portions embracing the upper and lower edges of said traveler flange, and a sheet metal holder for said vertical flange ring comprising a body portion apertured to receive the lower portion of the vertical flange of said ring and oppositely disposed and downwardly offset projecting portions directly egnaging the ring rail and supporting the body portion and ring spaced sulficiently above the rail to elevate all portions of the ring substantially above the ring rail and to provide substantial clearance between the lower portion of the traveler and. the ring rail, said traveler being also entirely clear of all parts of said holder.

2. In a ring spinning frame having a ring rail, a vertical flange ring having a supporting portion and having a traveler flange extending substantially above and below said supporting portion, a traveler for said ring having portions embracing the upper and 7 lower edges of said travelerflange, and a holder for said vertical flange ring comprising a body portion apertured to receive the lower portion of the vertical flange of said ring and having downwardly and outwardly projecting portions directly engaging the ring rail and supportii'ig the body portion and ring spaced sufficiently above the rail to elevate all portions of the ring substantially above the ring rail and to provide substantial clearance between the lower portion of the traveler and the ring rail, said. traveler being also entirely clear of all parts of said holder, and said projecting portions being adapted to be secured at spaced points to said ring rail. y

In testimony whereof I have hereunto affixed my signature.

JAMES F. MARSHALL.
